The marketing materials for this keyboard specifically reference its anti-ghosting technology - so one could enter as many keys at a time as they want. I've encountered this limit in a number of games, so I wonder if something like this would be perfect for gaming? That said, do most newer keyboards mitigate this problem? I haven't been serious about PC gaming in quite awhile

This keyboard works in Windows, and you can get all of the benefit of its great clicky, tactile feel. Just make sure you download and install the small and unobtrusive drivers from Matias.ca, or your KB won't work. BTW, the KB's 3 USB ports work fine under Windows (again, assuming you've installed the drivers).
